Disk washer and shell method
WebDec 11, 2015 · The Shell method approaches it from quite a different viewpoint. This time we end up with a set of hollow cylinders (something like a water pipe). You need to use different integration formulas for disks, washers and shells methods. See this page for explanation and examples of disk and washer methods: WebThe shell method allows us to calculate the volume of the solid of revolution of regions that are challenging to calculate using the dish or washer method. In the past, we’ve learned how to approximate the volume by cutting it into “slices” perpendicular to the axis of rotation.

We would need to split the computation up into two integrals if we wanted to use the shell method, so we’ll use the washer method. The area of a cross section will be A(x) = ˇ(2 x)2 ˇ p x 2 = ˇ 4 4x+ x2 ˇx= ˇ 4 5x+ x2: 1

This section … WebNov 10, 2024 · In this section, we examine the method of cylindrical shells, the final method for finding the volume of a solid of revolution. We can use this method on the same kinds of solids as the disk method or the washer method; however, with the disk and washer methods, we integrate along the coordinate axis parallel to the axis of revolution.
WebComment: An easy way to remember which method to use to find the volume of a solid of revolution is to note that the Disc / Washer method is used if the independent variable of the function(s) and the axis of rotation is the same (e.g., the area under y = f (x), revolved about the x-axis); while the Shell method should be used if the ...
